Need some electrical advice please. I have an AVan Erin Mark 2 poptop and I have just fitted a new Banten Antenna which is very good. I need to get 12 volts to it for the built in amplifier.
A potential source of 12 volt is the panel whose image I have attached to this post. It is easily accessible and is very close to where I need it so cabling etc should not be a drama. Ideally it would be great if the antenna only had power when the master switch on this panel was in the on position.
So can any of you folk with some electrical knowledge share your thoughts please?
Ryjoe . on the back of the main switch one wire will come from battery , you want to take your power from the otherside of the main switch ( use electrical terminals to join to this wire , then put an inline fuse ( probably 10- 15 or 20 amps - check your antenna rating and go a little higher ) this will protect you in the event of short circuit ... this is your positive wire for your antenna ... the negative wire of your antenna needs to be joined to the earth of your pop top .. or a wire back to earth on your trailer plug ... good luck

Most wiring for accessories will only be 10 or 15 amp cable, going higher to a 20 amp fuse then you'll risk frying the cable if there's a problem and this could cause a fire. The fuse is designed to be the weakest link, so it will blow if there's a problem but not if it has a higher rating than the cable. Going higher in fuses is not a good idea.

We sourced the 12 volt supply from the range hood and all is now completed and working fine. My son is an electrician so I got him to check my handiwork and he is happy with how it is done.
